Slightly change in relationship after 5ish months and sex. Thoughts?

I've (M28) been dating this girl (f24). started off thinking it's a fling. we kept talking over text and then met up moment Ramadan ended and kept meeting 2/3 times a week. We kept it to oral as I'm a virgin/Muslim. She's not a virgin.

Feelings amplified after our own holidays. I went to her house (big step for her she said). She said likes me a lot, would do anything for me sexually, missed me, see me in her future, brought a gift. This is two or three weeks ago. Then I finished her for the first time (hands) and I feel her getting more intense about me.

She then meets my friends for the first time. We get excited and have sex for the first time. She said she's scared that I'd regret it. I say I'll pull out coz I'm not wearing condoms and she said please coz he'll be in too much heat. She screamed she'd marry me / i drive her crazy, and I can finish and spit on her as she doesn't want it wasted. She calls me at 2am to check in, gets horny and fingers her self and says she cares a lot.

We've met three since but she seems more distant as her family life is busier rn (I mirror). Holds my hands / kisses but avoids it getting to heavy as it's near home. She says she's a bit confused but she's a confused person. Says she likes our relationship and cares for me / emotional connection but doesn't wanna get hurt or hurt me. She she'd break my dick, piano or egg my car if I break her heart (jokey tone). She wonders if it's only sexual chemistry but feels comfort / home with me. we should avoid sex as it's wrong but communicate and bring protection if it does happen. We've met on Friday for third time this week, and I brought her a flower / cookies, and she bought me a tin of tomatoes I like. She felt much more like normal and said she was overwhelmed by family stuff and opened up saying she thought she told Nd really wanted to see me earlier in the week coz I had a bad work day.

She's had an ex which didn't end well like three years ago. I'm new to things and relationships but assume this may be the honey moon ending and need to space things
